Specification of Letters Patent.

Patented Sept. 22, 1914.

Application flled December 27, 1913. Serial No. aos,94s,

To all whom it may concern Be it known. that I, 'WILLIAM H. TUOHY, a citizen of the United States and a resident Waulresha and new and useful Improvements in Concrete- Molds; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accom panying' drawings, and to the letters of reference marked thereon, which form'a part of this specification.

This invention relates to improvements in concrete molds and it includes improved features of construction applicable to molds used for the construction of single walls,',

and also to improvements by which such molds are particularly adapted for use in the construction of walls and foundations of buildings and similar structures wherein the double Wall construction is employed.

The object of my invention is to provide improvements in concrete molds embodying the general features set forth in my copending application filed on the 27th day of December. 1913, and bearing Serial No. 808.947. both with respect to the means for supporting and giving relative movement to the mold-boards of such molds. and with respect to means whereby the construction of double walls may be accomplished in an efficient and inexpensive manner.

My invention consists in the matters hereinafter described. more particularly pointed out in the appended claims. and illustrated in the accompanying drawings. in which- Figure 1 is a view in side elevation of one form of concrete mold. constituting my in vention; Fig. 9. is a top plan view of the mold illustrated in Fig. 1; Fig. 3 is a sectional view. taken on line 3-3 ofFig, 2; Fig. 4 is an enlarged detail plan view of a portion of-the mold and wall. and showing the first position of the mold in forming a corner; Fig. 5 is a sectional view taken on line 5-5 of Fig. 4g'Fig. 6 is a sectional view taken on line 6-6 of Fig. 4; and Flg. 7 is an enlarged detail plan view showing the position of. the mold in completing a corner.

Referring to the drawings, showing a pre ferred embodiment of my inventio-n, adapted for uQie inthe construction of double walls;'

the concrete mold illustrated comprises, in general, two pairs of mold-boards 10. 1! and 12, 13. The pairs of mold-boards are separated by a' space from each other. and each pair comprises two upright mold-boards arranged tobe. normally maintained in parallel relation, and spaced apart to form a space'the'rebetween adapted to receive concrete-for the construction of each portion of. the double wall. The mold-boards are supported in upright position by means of transversely extending frame members 14, pmvided-with downwardly extending ar ms torwhichsaid boards a'resecured. The arms supporting one mold-board of each pair are mounted in fixed relation to the frame members, and the arms supporting the other mold-board of each pair are pivotally mounted upon'the frame members to permit a limited movement of the board supported thereby, for a pur ose set forth in my separate application ereinbefore referred to. A manually operated means is further provided in connection with each frame member. for the purpose of simultaneously controlling the movemcnt of the pivoted arms and the mold boards secured thereto. Referring now to Figs'l, 2 and 3, wherein is shown a form of my device adapted for use in constructing walls of this double wall construction, an understanding of the features embodied therein may be had from the following description.

'The mold boards 10, 11. 12, 13, respectively, are of equal length and have their upper and lower margins in parallel relation. The spaces between the boards 10, 11 and 12, 13 are preferably of equal width, and the distance between the inner boards 11 and 12 corresponds with the desired width of the space between the parts of the double wall, to be formed by the use of the device-.

The upper margins of the mold-boards, by preference, lie in substantially the same hori zontal plane. The lower margins of the outer mold-boards 10 and 12, however, project some distance below the lower-margins of the inner mold-boards 11 and 1231s shown in 3. The purposeof this construction will be hereinafter pointed out.-

-. The frame members 14, 14, by means of which -the mold-boards are supported. cx-

tend transversely-oi. .the. said mold-boards and are spaced apart at. a suitable distance for properly suppcrting theboa'rds. and for eperating the mold.

Each frame member comprises a rectangular structure consisting of pairs of horizon:

tal bars '15 and 16 arranged in parallel relation one above the ,othenand rigidlv consaid arms extending downwardly below the lowermost frame bar 16 and supporting at their lower extremities the several mold boards, there being provided suitable means for securing said arms to the outer faces of the moldboards. Two of these arms,

namely 19 and 20, are secured in fixed relation to the frame and extend between the upper and lower horizontal bar members 15 and 16; the same being rigidly held in position by means of a plurality of bolts 23 extending through said bar members 15 and 16 and the upper and mid-portions of said arms, The remaining arms 21 and 22 are secured to the frame members in a manner permit themto be oscillated through a -,limited distance.

The arm 21'is pivoted to the lower horizontal bar members 16 by means of a pivot bolt 24 and projects a distance above the upper bar members 15. The arm 22 in like manner is pivotally mounted between the lower bar members 16 by means of a pivot bolt 24, but terminatesbetween the upper horizontal bar members 15. The arms 21 and 22 support the mold-boards 10 and 12, respectively, and are adapted to be adjusted for the purpose of swinging said boards through a limited distance, in a direction to and from the boards 11 and 13.

For the purpose of actuating the pivoted arms 21 and 22, I employ mechanism as follows: Rigidly fixed to the frame members 1 is an arm 25 which projects above the upper horizontal bar members and terminates in horizontal alinement with the upper extremity of the arm 21. The fixed arm 25 is located between the movable arms 21 and 22 and has attached to it one end'of a turn buckle-26 of ordinary construction. The other end of said turn-buckle is secured to the upper extremity of the pivoted arm 21. The said arms 21 and 22 are connected together by means of a horizontal connecting link 27, secured to said arms immediately below the upper horizontal bar members 15. By'revolving the turn-buckle in the proper direction the same may be expanded or contracted in a manner well known, acting to transmit a movement to the upper end of the movable arm 21 to swing the same about its pivot bolt 24. This movement is simultaneously transmitted to the arm 22 through the medium of the connecting member 27. By this arrangement the movable arms 21 and 22 remain constantly parallel and are controlled imultaneously by the manipulation of the turn-buckle 28.

The operation of constructing a wall of the before mentioned double-wall construction, is accomplished by the repeated use of the device hereinbefore described, and in the following manner: Iii-Figs. 1, 2- and 3 is showna portion of a wall 30 already completed, with'the mold secured thereto and in position to receive'concrete for the formation of a section of the wall to be superimposed upon the said completed portion of the wall. 'To secure the mold in position the turn-buckle is manipulated sothat. the movable mold-boards 10 and. 12 are swung in a direction away from the stationary mold-boards 11 and 13, respectively, as shown in the dotted line of Fig. 3. By this operation the space between the pairs of mold-boards is increased sutficient-ly to allow the upper portions of the already completed portionvof the wall to passbetween the boards. The device is placed in position with the lower margins of the outer moldboards slightly overlapping the outer surface of each wall portion; the margins of the inner mold-boards, by preference, coincidin with the adjacent upper andinner margins of the wall. Now, by 'agairlmanipulating the turn-buckle the movable mold-boards are-drawn inwardly a ainst the outer faces of the wall portions,\ t ie result. being that the fmold becomes firmly clamped to the wall and in a position to be filled with concrete in the usual manner.

The engagement of the outer mold-boards I with the wall is ,sufiicient to retain the mold firmly in position and for that reason it is unnecessary' that the inner mold-boards should extend downwardlyin a manner to overlap the inner surfaces of the wall. The concrete having hardened sufficiently, the mold is released from its clamping engage- ,ment with the wall by manipulating the turnbuckle to swing the boards 11- and 12 outwardly in the manner stated The mold may now be advanced to a position "where the ends cit-he mold overlap the ends of the wall portions just completed, the mold clamped in that position, and the operat on again'repeated to form the next succeeding section. a

A mold provided with moldboards of equal length, as illustrated in Figs. 1 to 3, is

molds for forming corners or intersections,

I provide, as a further feature of my invenupon the thickness of the wall portions and bers 36. At the upper portions of the said thereto. In addition to the gate-members, I provide the outer board 34 of the shorter pair of mold-boards with a rectangularly shaped rabbet 39 (Fig. 6), located in the lower margin of the board and preferably 1 formed by removing a rectangular portion l of the board adjacent to its end. The length of the rabbet is slightly greater than the thickness of the wall portion to be formed thereby and of a height equal to the distance j the said board overlaps the wall when the l mold is clamped in horizontal position there- I tion, a. mold embodying such features as to render it suitable for successfully oyercomj ing the objectionable feature mentioned in 1 the forming of intersections, without interfering at the same time with its adaptability for use in forming the straight or continu' ous portions of the wall. This purpose is accomplished by the addition of several novel features that are shown in Figs. 4 to 7 it being, understood that the constructidn of the moldin this instance is like that hereinbefore described, except with regard to the features hereinafter pointed out. To accomplish the purpose desired, I provide two pairsof mold-boards 31, 32 and 33, 34, of which the boards of at least one pair, 31 and 32, extend or project at their ends a predetermined distance beyond the extremities of j the other pair of mold-boards 33 and 34. In

to. Rabbeting the mold-board in this manner has the efiect of reducing the end portion of said board throughout the rabbeted portion to a height equal to that of its companion, the mold-board 33. The purpose of the rabbet will be apparent as I proceed with the description of the operation of the mold in constructing or two walls.

Describing the the preferred construction shown (see Figs. forming the intersection of 4 and 7), one pair, 31 and 32, of the mold- 1 boards is made longer than the other pair. 1 and projects at both ends beyond the ends of l the other pair. The distance that the ends of said pair of mold-boards 31, 32 projects beyond those of the other pair is dependent operation of joining the portions of a wall, intersecting at right angles, it is to be assumed that the portions 40 and 41 have already been constructed and a superimposed section is to be formed. To perform the first step in the operation of constructing the intersection or corner, the mold is claimed to one of the intersecting portions of the wall, in a manner already suggested, and in such position that the ends of the mold-boards project slightly. beyond the ends of the wall portion to which the mold is clamped and likewise beyond the portion ofthe wall intersecting the same at right angles thereto, as shown in Fig. 4. The placing of the mold in this position is made possible by the increased length of the outer pair 'of moldeboards 31 and 3-2 and also by reason of the presence of the rebate 39 in one of the shorter pair of mold-boards 34, in that the intersecting portion of the wall 41 embraced by the recess, thus permitting the end of the board to extend over the said wall portion and the mold to assume its proper horizontal position, which otherwise would not be possible, owing to interference of the said intersecting portion. Having clamped the mold in position, the gatemen1bers are inserted in the ends of, the mold-boards for the purpose of formiug the end surface of the section to be formed. By reason of the fact that the mold-boards project beyond the ends of the wall, as suggested, the gate-members may be placed in position, and the alineinent of the inner faces of the gate-member with the outer faoes of the intersecting wall portion is assured The mold is now ready to re ceive the concrete to form the superimposed sections 12 and 43 (Fig. 5). After the con-. crete has hardened sufiiciently the mold is removed and transferred to the intersecting i portions of the wall and in a position' at i right angles to the sections 42 and 43, just the space separating them, but in any parl ticular instance the distance is substantially i equal to or slightly greater than the distance separating the walls plus the thickness of one of the wall portions. At the adjacent l extremities of the pairs of mold-boards and j at one end of the mold, I provide gate-members 35, 35 (Figs. gt and 6), which may be removably inserted at the ends of and between the mold-boards. the same acting to provide a vertical end face at one of the ends 1 of each section of the wall formed by the l mold.

As a preferable construction for the gatei members and means for removably securing them in place, the ends of the mold-boards are provided with angle members 36, secured to the outer faces of the boards. The angularly bent portion of said angle members project inwardly toward each other and at a distance beyond the ends of the boards. In this manner a vertical space is formed be" tween the said bent portions of the angle members 36 and the ends of the boards. The gate a member, preferably rectangular in shape, is provided with metal flanges 3T. sccured to the. lateral margins of the outer faces of the gate-member and projecting outj wardly therefrom, and adapted to c'tga the said s 'iaces formed by said angle memgate-members, are provided stops 38. adapted to engage the upper margins of the moldl boards, and acting to limit the downward l movement of the gate-members, within the spaces. These stops are preferably formed by bending an upwardly extending portion of the flange members 37 at right angles formed. In this position, however, the opposite ends of the mold-hoards, not pr0- vided with the gate-members, are placed in abutting relation to the sections 42 and 43 (Fig. 7), so that the space between the mold-boards extends up to the section just formed. In this position the mold is filled with concrete and when hardened produces a section joining the section previously formed, in a proper and worlunanlike manner. By this arrangement of the moldboards, it is seen that the construction of a wall having smooth and regular corners or intersections is easily and successfully accomplished. without the aid of any additional molds or equipment or in any way decreasing the suitability of the mold in the formation of the linear portions of the wall. In the construction of the straight or continuous portions of the wall, it is only necessary to overlap a greater extent the ends of the longer mold-boards upon the extremities of each preceding section to compensate for the additional length. The gate-members 35 may also he provided upon the form of mold provided with mold-boards of equal length (Figs. 1 and 2), for the purpose of formingspaces or openings in the wall, where it is desired to place windows or doors in the wall. In this instance, the gate-members act to provide a smooth end surface to the sections of the wall terminating at either side of the opening formed.

A concrete mold, embodying the features of my invention, has the advantage of he-- ing capable of easy and rapid adjustment and removal whereby the work can be accomplished with great speed and with comparatively small amount of labor and loss of time. Its use eliminates the added expense and inconvenience of providing and manipulating special molds for forming corners and openings. as before pointed out.

The device herein illustrated and described may be variously modified in the de tails of construction without departure from the spirit of the invention, and for that reason I do not wish to be limited thereto, ex cept so far as pointed out in the appended claims.
